Any reason why the Fire Stick 2nd Gen can't just jump to latest firmware?

Updating my 2nd Gen firestick for my GF to use. Hasn't been used for quite a while. Why in gods name can't it just install the latest firmware? So Far I think it's installed 5 firmware updates. I'm currently up to 5.2.67 Jesus Christ!!! This is getting ridiculous! Amazon ever heard of Cumulative updates!!!!!!!!?!?!

They're hoping you'll give up and just buy a new one.
